jpa Table per concrete class inheritance strategy
30% OFF - 9th Anniversary discount on Entity Framework Extensions until December 15 with code: ZZZANNIVERSARY9
Remarks
- Vehicle, TransportationVehicle and PassengerVehicle are abstract classes and they will not have separate table in database.
- Truck, Car and Bike are concrete classes so they will be mapped to corresponding tables. These tables should include all the fields for classes annotated with @MappedSuperClass because they don’t have corresponding tables in database.
- So, Truck table will have columns to store fields inherited from TransportationVehicle and Vehicle.
- Similarly, Car and Bike will have columns to store fields inherited from PassengerVehicle and Vehicle.
